Who was Grace Hopper? A software tester, workplace jester, cherished mentor, ace inventor, avid reader, naval leader—AND rule breaker, chance taker, and troublemaker. Grace Hopper coined the term “computer bug” and taught computers to “speak English,” and throughout her life succeeded in doing what no one had ever done before. Delighting in difficult ideas and in defying expectations, the insatiably curious Hopper truly is “Amazing Grace” . . . and a role model for science- and math-minded girls and boys.

    And, it's true, many of them do. But Paul Erdos never followed the usual path. At the age of four, he could ask you when you were born and then calculate the number of seconds you had been alive in his head. But he didn't learn to butter his own bread until he turned twenty. Instead, he traveled around the world, from one mathematician to the next, collaborating on an astonishing number of publications. With a simple, lyrical text and richly layered illustrations, this is a beautiful introduction to the world of math and a fascinating look at the unique character traits that made "Uncle Paul" a great man.

    They experiment, explore, test, and play, and they learn a great deal about problem-solving through questions and hands-on experiments. They don't see lines between disciplines; rather, they notice interesting materials and ideas that are worth exploring. This book is about creative experiments, in all fields, that help kids explore the world.Children gravitate toward sensory experiences (playing with slime), figuring out how things work (taking toys apart), and testing the limits of materials (mixing a tray of paint together until it makes a solid mass of brown). They're not limited by their imaginations, and a wooden spoon can become a magic wand as quickly as a bag of pom-poms can become a hot bowl of soup. This book is about helping parents and teachers of babies, toddlers, and preschoolers understand and tap into this natural energy with engaging, kid-tested, easy-to-implement projects that value process over product. The creative experiments shared in this book foster curiosity, promote creative and critical thinking, and encourage tinkering--mindsets that are important to children growing up in a world that values independent thinking.In addition to offering a host of activities that parents and teachers can put to use right away, this book also includes a buffet of recipes (magic potions, different kinds of play dough, silly putty, and homemade butter) and a detailed list of materials to include in the art pantry.
